### Please describe the problem.

once in a while we have those two tests failing in daily testing of git-annex on ndoli under tmp.  The test configuration is "prescribed" [here](https://github.com/datalad/git-annex/blob/master/clients/clients.yaml#L10) but overall -- we run `git annex test` under POSIX partition on that host.  As a result we get sometimes (not daily!)

```
❯ grep FAIL git-annex-tmp.log
    conflict resolution (removed file): FAIL (1003.88s)
    conflict resolution (mixed directory and file): FAIL (1380.03s)

and among clients it happens only on ndoli and only rarely:
